FIG. 8 is a flowchart of the trimming processing S1 performed by the apparatus 1. The procedure of the trimming process S1 will be described with reference to FIGS.

  First, the workpiece W is set on the workpiece guides 11 and 12 waiting at the positioning position (S1-1). At this time, the work guides 11 and 12 align the bottom surface and the left side surface so that the outer shape of the work W has a substantially cubic shape, and positions the work W at a predetermined position. The activation SW is turned on (S1-2), the drive motors M1 to M4 are activated, and the circular saws 31L, 31R, 33U, and 33D are rotated (S1-3). Then, the workpiece W is clamped by the clamping means 2 (S1-4, FIG. 7C). In order to secure the moving path of the cutting means 2, the work guides 11 and 12 are moved from the positioning position to the retracted position (S1-5, FIG. 7B).

  Next, the left and right end cutting units 31 at the storage position P1 perform a series of reciprocating motions by the back-and-forth reciprocating mechanism 41, and move the workpiece W to a predetermined length while moving from the standby position P2 before cutting to the standby position P3 after cutting. (S1-6 to S1-11). After the cutting is completed, the drive motors M1 and M2 are stopped (S1-9). Thereafter, the upper and lower end cutting unit 34 of the storage position Q1 performs a series of reciprocating operations by the left and right reciprocating movement mechanism 42, and cuts the workpiece W to a predetermined width while moving from the standby position Q2 before cutting to the standby position Q3 after cutting. (S1-12 to S1-17, FIG. 7A). After the cutting is completed, the drive motors M3 and M4 are stopped (S1-15).

  The cut workpiece W is supported at the bottom and left side by the work guides 11 and 12 moved from the retracted position (S1-18, FIG. 7C). Clamping by the clamping means 2 is released (S1-19). Then, the workpiece W trimmed to a predetermined processing dimension is taken out from the workpiece guides 11 and 12 (S1-20). At this time, the plurality of thin plates 5 constituting the workpiece W are trimmed to uniform processing dimensions.

  According to this trimming apparatus 1, once clamping is performed, even if the cutting is performed along the other direction, there is no need to re-clamp, so it is possible to eliminate the deviation, and trimming processing with excellent processing accuracy can be achieved. It becomes possible. Further, the processing accuracy of the plurality of thin plates 5 can be made uniform. Furthermore, for example, even a thin sheet material having a high moisture content and low wrinkles in a free state can be operated in a state where a plurality of sheets are stacked, so that the possibility of material breakage (cracking, etc.) is reduced. Further, even with the same thin plate material, trimming can be performed by one operation, so that the possibility of material breakage (cracking, etc.) is reduced. In addition, since the workpiece W is clamped by the clamping portion 21 that is in surface contact with the size corresponding to the trimming dimension, trimming is possible in a state where the “warp” and “distortion” of the material are extended, so that trimming with excellent dimensional accuracy is possible. Processing becomes possible.
